TSI Alnor HM685 Hydronic Manometers for System Balancing

TSI Alnor HM685 hydronic manometers are used to balance steam and hot water heating systems, chilled water cooling systems, and to check pump performance. Balancing these hydronic systems reduces energy consumption and saves money.

The HM685 can measure and display differential pressure, high side gauge pressure, and low side gauge pressures simultaneously without the need to change hose connections or instrument valve settings. Enter a valve manufacturer's Cv flow factor into the HM685, and it will display a volumetric flow up to 100 Cv.
